"But, the bigger news under the hood is the turbocharged motor in the Cooper S. While it does not use the Valvetronic system and only has VANOS on the intake side, it carries its own host of innovations....."

According to Miniusa.com the MCS does have valvetronic... who is right?

 

Sports Car International

Where does Miniusa.com say it?

 

According to the press kit/literature (literally a big book of stuff) we all got in Barcelona, it's vanos for the intake cam on the MCS and Valvetronic on the MC.

Per

 

under the performance specs... here is the article its a nice read otherwise...

 

Great article! Thanks for posting the whole thing.
There goes their newsstand sales to the Mini bunch! (JOKING!)
SCI is a great magazine. I subscribed for many years. They test/review a lot of cars, many of them highly exotic and $$$. I consider their basic stamp of approval to be an excellent sign, way beyond Road & Track, etc.
Waiting for that phone call... "Yer Mini is in!" YEAH!!

 

I guess you are saying that MINIUSA.COM says the MCS is Valvetronic under the performance specs for the MCS.

It does say fully variable valve timing which is VANOS. Valvetronic is fully variable valve lift which the MCS does not have. The magazine article is fully good on what it says about the two engines and does not appear in conflict to anything on Miniusa I can find. Where exactly are you looking?

Update: I looked at the inital press releases and the MC has variable lift on intake and variable timing on intake and exhaust. MCS has variable timing on intake only. I have read elsewhere that VALVETRONIC is not yet capable of the performance level for the higher performance BMW engines and working well with the direct injection turbo. The 335i does not have VALVETRONIC either.

 

possibly the confusion is over what is valvetronic and what vanos is.

in short Vanos= vtec-or i-vtec it is variable valve timming


Valvetronic- is a system that would take me 3 paragraphs to explain... but here goes the most lamens term i can put it. Valvetronic will vary the valve events So much that the car doesn't need a throttle body. On a valvetronic motor the throttle body stays wide open unless there is a valvetronic failure. The timing of the valves is alterd so much that it can regulate the airflow into the engine without the need or use of a throttle body. If there is a valvetronic failure... Then the throttle body will operate as it does on a current r50 r52 r53 and the car can be driven to the dealer under its own power.

sometimes people read valvetronic and think vanos, and vice versa...

 

Very interesting stuff!
